DESCRIPTION
● maintaining uninterrupted power sup-
ply of a single-phase receiver,
● three-phase power supply L1-L2-L3
(L1-priority phase),
● automatic phase switching during po-
wer supply failure or its value decre-
ase below 180 V AC,
● switching time at a level of 150 ms
● voltage switch threshold, switching
time and voltage hysteresis have de-
fault settings and cannot be changed
by a user,
● high voltage measuring accuracy – re-
lative error < 1%,
● voltage measurement of distorted si-
gnals (True RMS),
● output load– maximum 16 A for AC1
loads,
● signalling the parameters of particular
voltage supply phases – 3 x LEDs,
● mounting in distribution boards (TH35
rail) – width of 2 modules.
The automatic phase switch APM-20 is
designed to ensure uninterrupted power
supply of a one-phase receiver in case
of phase loss or RMS voltage value de-
crease below the norm. The main ad-
vantage of the device is a small relative
voltage measurement error, which does
not exceed 1% even for highly distorted
waves. The above is a result of an im-
plementation of the True RMS converter.
The APM-20 device is supplied by three
phases L1, L2, L3 with the L1 phase as
the prior one. The voltage switch thre-
shold (180 V AC), switching time (150
ms) and voltage hysteresis (10 V AC)
have default settings and cannot be
changed by a user. Each phase parame-
ters are optically signalled by means of
LEDs on the front panel of the device.
The internal system of output contacts
assures an increased resistance to their
bonding and protects against phase-to-
-phase short circuit. The maximum out-
put capacity should not exceed 16 A for
AC1 class receivers. APM-20 is mounted
in distribution boards (TH35 rail). The ca-
sing has the width of 2 modules.
